Evidence of Both Surface and Bulk Dirac Bands and Anisotropic Nonsaturating Magnetoresistance in ZrSiS

Abstract

ZrSiS materials show unsaturated magnetoresistance until a magnetic field of 53 T with a butterfly-shaped angular dependence. Intense Shubnikov-de Haas oscillations resolve a bulk Dirac cone with a nontrivial Berry phase. Combined with angle-resolved photoemission spectroscopy and theoretical calculations, ZrSiS is proved to be a Dirac material with both surface and bulk Dirac bands.
